To all whom it may concern:

Be. it known that'I, 'FRANK-:L. MoRsE', a citizen of the United States, residing at Ithaca, in the 'countyof Tompkins and State of New York, have invented a certain new and useful Improvement in Valve-Operating Mechanism, of which improvement the following is a specification. I

This invention relates to mechanism for operating valves of the rotary or oscillating cylindrical type, such as used in connection with engines, pumps, or other fluid pressure devices in which the valve is adapted to be driven continuously through its successive traverses, while the machine is running.

The principal objectof my invention is to prevent irregular wear of the .valve upon its seat, and it comprises means for producing a relative longitudinal movement be tween the valve and its seat at the same time that the valve is being rotated or oscillatedf for the proper distribution of the fluid through the admission anddischarge ports 4 of the motor, whereby thetrack of thevalve is shifted and no given point describes ex actly the same path'during' the successive traverses of the valve. This produces a continuous polishing action between the valve and its seat, resulting in uniform. wear. y In the accompanyingdrawing, I havev illustrated my improvement in connection with a gas engine having separate supply and exhaust valves ofthe rotary'cylindrical type, although it'is not limited to this construction.

Figure 1 is an elevation of the engine and valve operating mechanism embodyingmy improvement; Fig. 2, a transverse section of a portion of the engineshowing one of the valves; Fig. 3, an elevation at right angles to Fig. 1, a portion being shown in longitudinal section in a plane substantially in line with one of the-valves; and, Fig.4, 7 a plan of the valve operating mechanism.

According to the construction shown in the drawings, the engine, 5, is provided with separate supply and exhaust valves, 6 and 7, which are of the rotary cylindrical type mounted in corresponding seats at 010- posite sides of the engine cylinder and driven by a chain, 8, passing over a, sprocket or gear wheel, 9, on the crank shaft, 10 and sprocket wheels, 11 and 12, keyed upon the the chain, 8,passes. I I

The rotatable heads, 15 andl6, are preferably mounted in hearings in a frame or s ediadauo j f tet ersratnt! v -ERatented-($615.19;1915.

respective valves, 6 and I During the j running of the engine, the valves, 'by means "of thlSTIIlGGlll-IIISIH, operate -cont nuously through the1r successive traverses orre'voo lutions' to effect the proper opening and closing of theadmissionxand discharge ports of, the enginecylindera 7 1 .Inorder to produce; a'uniform wear of the valve upon its seat, in accordancewith my -invention,--any suitable means may be employed for effecting an 'endwise or long1- tudinal movement of the valverelative to its producing this result, the"valves may be prov1ded,; at thelr ends, with flanges or heads, 6Pand'7, tofwhich are pivotally-con nected the link bars, 13 and 14, respectively,

seat duringth'e successive traverses or revo- ,lutions, and as a preferred; mechanism for Q.

the point of connection-being at one side of the center or the axis of the valve. 1 In this way the link bar willproduce anendwise or during the. 'successive revolutions,-the oppo site end of the respective link bars may be 'pivotally connected"- to" the rotatable heads .or disks, 15 and 16," driven by the respective j sprockets, 17 and Y18, chain, 19, andsprocket,

bythe idler sprocket gear, 22,'*over which yoke, 23, and in; line with the axes of the respective valves, 6 and 7, and the link bars are connected to the beads by ball and socket joints at points outside of the axis-of rotation, so that, as the head,15, rotatesat a different rate'of speed from the valve, it'willf be seen that the angle of inclination of the link bar, 13, will be constantly changing,

thereby producing a: corresponding longitudinal movement of the valve during its suecessive revolutions.

Any desired ratio between the sprocket gears, 20, and 17 and 18, may be employed to produce the preferred difl'erence in the rate of rotation between the disks. 15, and 16, and the valves,whereby the track of the valve is constantly shifted and any given point will not describe the same path during the successive revolutions of the valve. This produces a continuous polishing action be-' tween ,the valve and its seat, resulting in I I20, mounted on shaft, 21, which is driven .7

uniform Wear, and increasing the periods of time during which the valves may be used Without refitting and other repairs.

Having now described my invention, What I claim as new and desireto secure by Letters Patent is:

1. In a valve mechanism, the combination Witha cylindrical valve and sea-t, of a driving connection for turning said valve, and

means cooperating with said driving connection for efiecting a relative longitudinal movement between the valve and seat to shift the path described during its successive traverses.

2. In a valve mechanism, the combination With a rotary cylindrical valve and seat, 01" a driving connection for rotating said valve, and means cooperating With said driving connection for effecting a relative longitudinal movement between the'valve and seat to shift the path described during its successive revolutions.

3. In a valve mechanism, the combination With a rotary cylindrical valve and sea-t, of a driving connection for rotating said valve, and means operating automatically to shift the valve to change the path described by a given point thereof during the successive revolutions. v a i. In a. valve mechanism, the combinatio with a rotary cylindrical valve and seat, of a driving connection for rotating said valve, a link bar pivotally connected at the end of the valve, and means cooperating with said driving connection for actuating said link Copies of this patent may be obtained for bar and causing a longitudinal movement oi the valve during its successive revolutions. 5. In a valve mechanism, the combination with a rotary cylindrical valve and seat, of

a driving connection for rotating said valve, and a link bar eccentrically connected by a universal joint at the end of the valve for causing a longitudinal movement thereof.

6. In a valve mechanism, the combination With a rotary cylindrical valve and seat, of a driving connection for rotating said valve, a. link bar eccentrically connected by a universal joint at the end of the valve, and means for moving the other end of the link bar ,at a different rate of speed.

7. In a valve mechanism, the combination with a rotary cylindrical valve and seat, of a driving connection for rotating said valve, a rotatable head opposite the end of the valve, and a link bar having a pivotal con nection at one end to the valve and at the other end to said head.

8. In a valve mechanism, the combination With a rotary cylindrical valve and seat, of a driving connection for rotating said valve, said valve having a flange at its end, a rotatable head opposite said flange, means for rotating said head at a diiferent rate of speed, and a link bar having universal joint connections eccentrically to said flange and head.
